6166	Fluid/Examples/PumpingSystem can't be simulated	victor	Andreas Heuermann	"When trying to run /Fluid/Examples/PumpingSystem.mo in OpenModelica v1.16.0-dev.beta1 (64-bit). I get errors and can’t start the simulation. It's the same for latest v1.16.0.

Forum post about the same issue: https://www.openmodelica.org/forum/default-topic/3118-fluid-examples-pumpingsystem-can-t-be-simulated
I can be contacted there is for information is requierd

{{{
[1] 14:48:00 Symbolic Warning
The model contains alias variables with redundant start and/or conflicting nominal values. It is recommended to resolve the conflicts, because otherwise the system could be hard to solve. To print the conflicting alias sets and the chosen candidates please use -d=aliasConflicts.

[2] 14:48:00 Translation Error
Internal error IndexReduction.pantelidesIndexReduction failed! System is structurally singular and cannot be handled because the number of unassigned equations is larger than the number of states. Use -d=bltdump to get more information.

[3] 14:48:00 Translation Error
post-optimization module replaceHomotopyWithSimplified (initialization) failed.

[4] 14:48:00 Translation Error
No system for the symbolic initialization was generated
